ELECTRICAL GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 252,848, dated January 24, 1882.

Application filed August 18, 1881. (Model.)

[[ all whom it may concern Be it known that I, JEROME BEDDING, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Electrical Gas-Burners, of which the following is a specification.

This invention relates to that class otelectrical gas-burners which are composcdin part ota tube orsection ot'insulating material-such as porcelain or glassattached to the gas-pipe and supporting the burner-tip, and provided with electrodes for lighting the gas-jet by induced currents of electricity.

The chief object of the invention is to enable a common lava tip to be inserted in and removed from the insulating section without disturbing the connection of the electrodes thereto, thereby enabling any desired tip to be applied to the section, and enabling one tip to be changed for another adapted to give a different form to the flame.

The invention also has for its object to provide improved means for securing the electrodes to the insulating section, and to adapt the latter for the reception of the electrodes.

To these ends my invention consists in the several improvements which I will now proceed to describe and claim.

Ofthe-accompanying drawings, form ing part of this specification,Figure 1. represents a side elevation ofagas-burner embodying my invention. Fig. 2 representsa top view of the same. Fig. 3 represents a section on line a 00, Fig. 2. Fig. 4 represents a side elevation of the insulating section and its electrodes before the application of the lava tip. Fig. 5 represents a longitudinal section ot'the same. Fig.6 represents a section on line 3 3 Fig. 5. Fig. 7 represents a longitudinal section of the insulating section without the electrodes. Fig. 8 represents a section on line 2 c, Fig. 7.

The same letters relate to the same parts in all the figures.

In the drawings, (t represents the insulating section or tube of a gas-burner of the class above described, the same being composed of porcelain or other suitable material.

and outside of the socket I aifix to the section a the electrodes (1 (l, the latter being so secured that the tip can be applied and removed without disturbing the connection of the electrodes to the section a.- I secure theelectrodes to the section by means of a suitable waterproof yielding material, which also forms the socket b, the electrodes being embedded in said material, and the latter molded or formed to present a smooth yielding inner surface, adapted to accurately fit the tip and permit the latter to be readily removed. The best material of which I am aware for this purpose is asbestus paper saturated with linseedoil, and when this is used I prefer to form longitudinal slots or recesses c e in the interior of the upper end of the section a, said end being preferably tapered to correspond to the taper of the tip-c, but of larger diameter. The paper is wrapped around the portions of the electrodes which are to be embedded, and the electrodes so inclosed are placed in the slots 0 c, after which a collar or tube of the paper is placed in the tapered portion of theinterior of the section a. and pressed closely against said portion, so that it forms the socket b. The socket thus formed is of a slightly yielding nature, so that when the tip is pressed into its place the leakage of gas between the tip and socket will be prevented. This material, being both water-proof and a non-conductor of electricity, not only insulates the electrodes, but also prevents any moisture which may be in or upon the material of the section a from conducting the electric current from one electrode to the other through the section a, and so interfering with the lighting of the gas by preventing the passage of a spark between the slightly separated ends of the electrodes at the orifice ot' the tip.

It will be observed that by adapting the section a to hold a lava tip and permitit to be removed and replaced by any other without disturbing the connection of the electrodes, I enable the section a to be sold as an article of manufacture and used with a tip having any desired form of gas orifice, and that in case achange is desired in the form of the flame after the burner has been applied it can be effected by simply substituting a new tip for the original one without requiring the removal of the section a. Heretofore in gasburners of this class the section a and the tip have been rigidly connected, so that they could notloe separated excepting with much difficulty and risk of breakage.

Having thus described my invention, I claim- 1. As an article of manufacture, an insulating section for gas-burners,having a yielding socket, substantially such as herein described, adapted to receive and permit the removal of a common lava tip, and electrodes secured to said section outside of the socket, as set forth.

2. The combination of theinsulating' section, having a yielding socket adapted to receive and permit the removal of a common lava tip, and electrodes secured to said section outside of the socket by a waterproof cement, substantially such as described, in which said electrodes are embedded, substantially as and for the purpose described.

8. The improved molded insulating section or tuhefora gas-burner,having slots or grooves made on its inner surface at its upper end for the reception of the electrodes and the cement or material whereby said electrodes are secured, as set forth.

In testimony whereofI have signed my name to this specification, in the presence of two subscribing witnesses, this 16th day of August, A. D. 1881.
